DETAILED DESCRIPTION

For some embodiments, methods and apparatuses of enabling displayingmerchandise related information to consumers using digital signage unitsare disclosed. The merchandise related information may be associatedwith retailers, advertisers, brand managers or any entities that desireto present the merchandise related information to the consumers usingone or more signage units installed at positions where the merchandisesmay be physically displayed. The digital signage unit may be configuredto operate independently or together with other digital signage units.The digital signage unit may include at least a processor, acommunication module and a display. In addition, the digital signageunit may communicate with a server computing system to receive themerchandise related information which may include pricing informationand advertising information.

In the following description, numerous specific details are set forth,such as examples of specific data signals, components, connections, etc.in order to provide a thorough understanding of the various embodimentsof the present invention. It will be apparent, however, to one skilledin the art that the embodiments of the present invention may bepracticed without these specific details. In other instances, well knowncomponents or methods have not been described in detail but rather inblock diagrams in order to avoid unnecessarily obscuring the embodimentsof the present invention. Reference may be made to the accompanyingdrawings that form a part hereof, and in which it is shown by way ofillustration specific embodiments in which the invention can bepracticed. It is to be understood that other embodiments can be used andstructural changes can be made without departing from the scope of theembodiments of this invention. As used herein, the terms “couple,”“connect,” and “attach” are interchangeable and include various forms ofconnecting one part to another either directly or indirectly. Also, itshould be appreciated that one or more structural features described inone embodiment could be implemented in a different embodiment, even ifnot specifically mentioned as being a feature thereof. Thus, thespecific details set forth are merely exemplary. The specific detailsmay be varied from and still be contemplated to be within the spirit andscope of embodiments of the present invention.

Described herein are embodiments of a micro digital signage (MDS) unitconfigured to primarily deliver information to consumers in areas wheremerchandises may be displayed. One example of such an area is aretailer's store. The retailers can benefit from using the MDS units toimprove customer service, improve pricing and coupon delivery andenhance a store's overall ambiance. The consumers may benefit byreceiving informative information (e.g., nutrition, discounts, recipe,etc.) delivered by the MDS unit non-intrusively via a display associatedwith the MDS unit. The MDS unit can therefore enhance the consumer'sshopping experience while promoting specials and products and enablingpricing strategies for the retailers. Further, the MDS unit may beconfigured to enable video analytics, shelf disarray notification,traffic pattern analysis, store heat maps of consumer dwell time, andother applications that are not possible with the static paper pricingtags as used today.

Turning now to FIGS. 1A-1C, FIG. 1A is a diagram that illustrates afront left view example of a micro digital signage unit, in accordancewith some embodiments. Diagram 100 includes a micro digital signage(MDS) unit having height 125, depth 130 and length 135. For someembodiments, the MDS unit is configured to fit on a display shelftypically seen in a retail shop such as, for example, a supermarket. Thedigital signage unit may be located at a shelf edge where the paperprice tags are typically used to display the price information. The MDSunit may be configured to provide the merchandise-related informationabout the products that are displayed on the shelves where the MDS unitis positioned. For example, the merchandise-related information mayinclude price, coupons, advertising, specials, manufacturer-providedinformation, social network information relative to the merchandise(e.g., like, reviews, etc.), merchandise-related games, etc.

The MDS unit may include camera module 138, a display 105, male pins 110and 115 and interface connector 120. The camera module 138 may be usedto collect video analytics. The display 105 may be a touch-sensitivedisplay and may be configured to display information independently ortogether with neighboring displays in a border-less configuration. Thedisplay 105 may be a color display. Using the touch-sensitive display105, a consumer may interact with the information being displayed. Forexample, the consumer may cause nutritional facts associated with a foodmerchandise to be displayed, or the consumer may playmerchandise-related games. Power and data may be transferred among aplurality of the MDS units through the interface connector 120. The malepins 110 and 115 may also be used to transfer low voltage power. The MDSunit may have a small form factor with, for example, the height 125 atapproximately 2 inches, the depth 130 at approximately ⅜ inch, and thelength 135 at approximately 6 inches.

FIG. 1B illustrates a front left view example of a section of a shelfthat may be used to attach to a MDS unit, in accordance with someembodiments. The shelf includes a shelf top 140, a front edge 145, and aside edge 151. Merchandises are typically placed on the shelf top 140,and price information is typically displayed on the front edge 145. Thefront edge 145 is considered to be an edge that is most visible to aconsumer. The front edge 145 is typically the edge that the consumeruses to took for price information. For some embodiments, the height ofthe display 105 (shown in FIG. 1A) is configured to be approximately thesize of the front edge 145. This may be advantageous because it enablesthe MDS unit to be attached to many existing shelves without requiringthe retailers to replace the existing shelves to accommodate the MDSunit. It may be possible that various products may be placed on theshelf top 140, and the display 105 may display information related to atleast one of those products.

FIG. 1C illustrates an example cross-section of the shelf. Thecross-section view illustrates top and bottom retaining portions 150 and155 which are designed to keep a paper price tag in place. As will bedescribed, for some embodiments, the retaining portions 150 and 155 maybe used with a retaining mechanism to keep the MDS unit in place.

FIG. 2A is a diagram that illustrates a front right view example of aMDS unit, in accordance with some embodiments. Diagram 200 includes aMDS unit similar to the MDS unit illustrated in FIG. 1. The MDS unit mayinclude interface pin receptacles 210 and 215 and connector receptacle220 on its right side. The interface pin receptacles 210 and 215 andconnector receptacle 220 may enable the MDS unit to interconnect to aneighboring MDS unit to its right. The male pins 110 and 115 and theinterface connector 120 may enable the MDS unit to interconnect to aneighboring MDS unit to its left. This enables interconnecting theplurality of MDS units. It may be noted that the number of male pins 110and 115 and the number of receptacles 210 and 215 may vary depending onthe implementations. For example, only one male pin and one femalereceptacle may be used, or multiple male pins and multiple femalereceptacles may be used.

FIG. 2B is a diagram illustrating an example of interconnecting aplurality of MDS units, in accordance with some embodiments. In thisexample, a row of four MDS units 240, 250, 260 and 270 are lined up andinterconnected to one another using their respective male pins 110, 115,interface connector 120, interface pin receptacles 210, 215 andconnector receptacle 220. The combination of the interface pins,connector and their corresponding receptacles provide a pathway for dataflow and electrical charging of the connected micro digital displayunits.

Since the display 105 of each of these MDS units 240, 250, 260 and 270may be configured to operate in the border-less configuration, theytogether form an extended or a virtually continuous border-less display.As an example, the MDS units 240 and 250 may operate independently ofall other MDS units by displaying the “text 1”, “text 2”, “image 1” and“image 2” information within their own displays. As another example, theMDS units 260 and 270 may operate together by displaying the “text 3”and “image 3” information across their display units. As anotherexample, the MDS units 240, 250, 260 and 270 may operate together bydisplaying the “this text is displayed across all signage units”information across all of their display units. For some embodiments, anobject displayed on the display of one MDS unit may be dragged anddropped into the display of a neighboring MDS unit. This may beconvenient for an administrator to rearrange the information to bevisible to the consumers. For some embodiments, the MDS unit may beplaced in an admin mode to enable an administrator to perform contentmanagement activities using the touch-sensitive feature of the display105. When appropriate, the MDS unit may be switched to a consumer mode.The setting of the appropriate modes may be performed by a systemadministrator using a server computer system (described in FIG. 7A).

FIG. 3 is a diagram that illustrates a back view example of a MDS unit,in accordance with some embodiments. Diagram 300 includes a MDS unitsimilar to the MDS unit illustrated in FIG. 1A. The back side 305 of theMDS unit may include multiple slots 320, 325, 330 and 335 configured toreceive a retaining mechanism. For some embodiments, the slots 320 and335 are generally vertical and positioned near the left and right sideof the MDS unit. The slots 325 and 330 are generally horizontal andpositioned near the bottom side of the MDS unit, as illustrated. Forsome embodiments, the back side 305 of the MDS unit may also include amechanical engagement mechanism or activator 310 to engage or disengagethe male pins 110, 115 and the interface connector 120. When theengagement mechanism 310 is in a first position (e.g., slide to a leftmost position), the male pins 110, 115 and the interface connector 120are extended out from the body portion of the MDS unit. When theengagement mechanism 310 is in a second position (e.g., slide to a rightmost position), the male pins 110, 115 and the interface connector 120are retracted into the body portion of the MDS unit.

The operation of the engagement mechanism 310 may help disconnecting orremoving the MDS unit from its neighboring MDS unit for maintenance.Accordingly, the MDS unit may be referred to as being field replaceable.This capability allows removing a MDS unit from a middle of a rowwithout disconnecting the entire row from one end to the other end. Itmay be noted that since each MDS unit is capable of operatingindependently, when one MDS unit is removed from a row, the remainingMDS units in the row may still be operable. When a row is interruptedbecause one MDS unit is removed, an emergency beacon may be generatedand transmitted to a server computer system in a back office. Further,when a row is interrupted, the power to one or more of the MDS units mayalso be interrupted. In this situation, the backup battery power onthese units may be used.

For some embodiments, the engagement mechanism 310 may be positionedwithin a slot 315 to enable the engagement mechanism 310 to be easilymoved to its various positions. The slot 315 may also help keep the backside 305 of the MDS unit generally flush. It may be noted that eventhough the slot 315 in the current example has a shape of an arc, othershapes are possible. It may also be noted that the position of the slot315 is only exemplary and other position may be possible.

FIG. 4 is a diagram that illustrates a top view of an example retainingmechanism, in accordance with some embodiments. The illustratedretaining mechanism 400 is a spring loading and locking mechanism thatincludes two connected arc-shape body portions connected to one anotherat an edge of the arc. Each of the arc-shape body portions may includetwo connectors for a shelf and two connectors for a MDS unit. Over all,the retaining mechanism 400 may include two sets of connectors. Thefirst set of connectors is configured to attach the retaining mechanism400 into a shelf edge. The second set of connectors is configured toattach the retaining mechanism 400 into the back side of the MDS unit.Referring the FIG. 4, the first set of connectors includes connectors460, 465, 470 and 475, and the second set of connectors includesconnectors 420, 425, 430 and 435. Each of the connectors in the firstand second sets may have a spring force to enable holding the connectorsin the MDS unit and in the shelf. For example, the spring force mayenable adjusting one arc-shape body portions to be flexible enough toinsert the connectors in the first set into openings associated with ashelf edge. Similarly, the spring force may enable adjusting the otherarc-shape body portion to be flexible enough to insert the connectors inthe second set into openings associated with a back side of the MDSunit.

FIG. 5 is a diagram that illustrates a bottom view of the exampleretaining mechanism, in accordance with some embodiments. It should benoted that the retaining mechanism illustrated FIGS. 4-5 is designed tokeep the MDS unit in place at the edge of a shelf such that the display105 of the MDS unit is visible to the consumer. The design of theretaining mechanism 400 may be dependent on the design of the edge ofthe shelf as well as the design of the back side of the MDS unit. Assuch, variations of the design of the shelf, the edge of the shelfand/or the back side of the MDS unit may necessitate appropriatemodifications to the retaining mechanism 400. Regardless of themodification, the function of the retaining mechanism 400 may be toattach the MDS unit to the edge of the shelf while allowing the removalof the MDS unit from the edge of the shelf for maintenance, replacement,etc.

FIG. 6 is a diagram that illustrates example components in a MDS unit,in accordance with some embodiments. An MDS unit 600 may include aprocessor 605, communication module 610, disconnection detection module615, display module 620, camera module 625, temperature and motionsensor 630, power module 635, interface module 640, and contentmanagement module 645. Although not shown, other modules may also beincluded in the MDS unit 600 to enable it to perform the functions asdescribed herein.

For some embodiments, the temperature and motion sensor 630 areconfigured to provide temperature and motion sensing capabilities.Although shown as one, there may be a separate temperature sensor andmotion sensor. The camera module 625 is configured to enable collectionof video analytics. The camera module 625 may also be configured toperform various other operations that take advantage of itscapabilities. The MDS unit may also be configured to gather data fromthe shelf. The data collected by the temperature sensor 630 and thecamera module 625 may be reported back to a server computer system(shown in FIG. 7A). The server computer system may also provide data(e.g., price, advertising, etc.) back to the MDS unit for display to theconsumers 780 (shown in FIG. 7A). The communication module 610 mayenable the MDS unit 600 to be connected to a network using WiFi(wireless fidelity, e.g., IEEE 802.11a-1999 or 802.11a, an amendment tothe IEEE 802.11 specification that added a higher data rate of up to 54Mbit/s using the 5 GHz band) or wired connection. The illustrateddisplay module 620 is configured to enable the MDS unit to have a colordisplay capability.

Power to the MDS unit may be provided and/or managed by the power module635. The power may include the battery power and power provided by thestore where the MDS unit 600 is located. For example, the power from thestore may be provided at an end of an aisle where the shelves and theMDS unit 600 are located, and the power may be transmitted through rowsof MDS units. The power may be normal power or low voltage power. Thepower may also be used to recharge the battery in the MDS unit. Theinterface module 640 may be configured to monitor and enable data to betransmitted to and received from the neighboring MDS units. Thedisconnect detection module 615 may be configured to monitor for anydisconnection that may occur within a row of MDS units and to alert theserver computer system of such disconnect.

The MDSunit 600 may also include memory to store instructions and applicationsto enable the processor 605 to perform operations related to the variousmodules contained within the MDS unit 600.

FIG. 7A is a network diagram that illustrates an example of componentsin a network that may be used to implement the MDS units, in accordancewith some embodiments. Diagram 700 may include a network within a storewhere multiple rows 720-760 of MDS units are employed. For someembodiment, the MDS unit located on the furthest right may be configuredto act as an access point to enable wireless communication to thenetwork via router 665. As described above, each MDS unit includes aWi-Fi capability. When disconnect occurs in a row of MDS units, theWi-Fi in the MDS units remained in the row may be turned on.

The network 705 may include a local area network (LAN), a wide areanetwork (WAN), 3G, 4G or a combination of these various types ofcommunication protocols to enable the MDS unit to communicate with theserver computer system and to any other network connected resourcesand/or services. For example, cloud-based resources and services may beavailable to enable the rich content related to the merchandises to bedisplayed on the display of the MDS unit within a store, within multiplestores belonging to a chain, within multiple stores located in ageographical area, and so on.

A server computer system 710 may be located, for example, in the backoffice of a store. The server computer system 710 may be connected tothe network 705 to provide data communication and content distributionto all of the MDS units installed on the shelves. The server computersystem 710 may be managed by an administrator or control agent 770. Theadministrator 770 may manage content that may be distributed to the MDSunits for display to the consumers 780. The content may be specificallycustomized for each MDS unit when the MDS unit is to display informationindependently of the adjacent MDS units. Alternatively or in addition,the content may be specifically customized for a group of MDS units whenthe displays of these MDS units are used to display themerchandise-related information as one extended display.

The server computer system 710 may also be coupled with cloud-basedresources and/or services accessible via the network 705. Some examplesof the cloud-based resources and/or services include ratings,advertising content, licensing and meta-data for video analyticscollection, etc.

Turning now to FIG. 7B, a method of enabling multiple displays to beused to display merchandise related information is shown. The method maycorrespond to the information described with FIGS. 1-7A. The method maybe implemented as a set of logic instructions stored in a machine- orcomputer-readable storage medium such as random access memory (RAM),read only memory (ROM), programmable ROM (PROM), flash memory, etc., inconfigurable logic such as programmable logic arrays (PLAs), fieldprogrammable gate arrays (FPGAs), complex programmable logic devices(CPLDs), in fixed-functionality logic hardware using circuit technologysuch as application specific integrated circuit (ASIC), CMOS ortransistor-transistor logic (TTL) technology, or any combinationthereof. For example, computer program code to carry out operationsshown in the method may be written in any combination of one or moreprogramming languages, including an object oriented programming languagesuch as C++ or the like and conventional procedural programminglanguages, such as the “C” programming language or similar programminglanguages.
